I recall similar at Twitter. Then sneering at hashtags in regular media etc. Magnified here by deliberately different "vibe", partly reaction to twitter. Moderation is going to be interesting, Bsky has become the provider, not just protocol as envisioned. Idea of 3rd party mod subscriptions broken.

Yes, this is the key thing I think, this behaviour has exposed the limitations of letting communities moderate themselves. It's less about moderation and more about the persecution of heresy. Bsky is going to have to do a lot of top down policy making as a result.
